thank you!! I understood Lenz's in situations where you were changing the field, but situations with magnets were confusing me so much and I couldn't find a guide that went over it in a straightforward way anywhere. you went through multiple situations! thank you!
Thank you. You explained this so well. I have always had an issue with fully understanding how the magnetic fields interact with one another and how the flux is involved.
Thank you so much for the very well and clear explanation. You helped me out of this slump of feeling like I couldn’t understand it to understanding it much much more. Thank you
Thank you for this video ...... It was really hard to find video which explained the concept in short amount of time ........ To which this video has done its job .
As soon as you put the B-field vector AND the delta-B vector in the same diagram, all of my misunderstandings of the concept for the past month went away instantly. Once again, a short RUclips video outperforms weeks of college teaching. Thank you!
Beautiful explanation and visualization, generally here it is not very easy to visualize but finally I have understood. Thank you, sir. Kindly be more active w/ yr content.
I was trying to solve these using the Fleming's right hand rule but found out that the direction of motion was the same as direction of the field so the induced current should be zero, but i want to know why the right hand rule doesn't work here.
I have a question sir. Suppose we have a frictionless system. Magnet and coil are arranged along the x-axis. If we move the magnet towards the coil in such a way that the north pole of the magnet faces the coil, the coil will oppose its motion and will generate the north pole. It will repel magnet. Then the magnet will move away. Then coil will oppose that too. So the magnet will move towards the coil and so on. We gave an initial push and the magnet started moving on its own. If magnet does so it will become self sustaining and will oppose the law of conservation of energy. So will the magnet do this or not and why? Please answer. My knowledge is not able to answer it. I love your lectures by the way. 🥰🥰🥰
Why does the galvanometer deflect to the right when pushing the north pole inside, since positive potential is on the left so it seems logical to me that it would point to the left? Btw. Great video.
Hi, I have a question. if the switch JUST got turned off on the solenoid, what would magnetic field on the solenoid be? it is going to be reduced, but still in the same direction I guess? (not looking at the inducing B yet. just the orignal B).
Why are the magnetic lines coming OUT OF N and going into S? Also, what I want to know is if you had a nail running through the coil and you applied a current to that coil, can you figure out which direction the nail would go? I would think yes, but I also get confused as the right hand rule has you placing your thumb in the direction of CONVENTIONAL current flow, from positive to negative, even though electrons ACTUALLY flow from negative to positive. So this confuses the heck out of me.
There are several conventions in physics that you have to learn. It's confusing at first but stick with and you'll remember them. 1) Magnetic field lines point away from N and towards S 2) For currents, you're right that it's the electrons that move in a conductor but we say that a positive current flows in the opposite direction. 3) Electric field lines point away from positive charges and toward negative charges. For the nail question you have to figure out the direction of the induced current in the nail. Then you'll the field produced by the coil and the field produced by the induced current in the nail. If the fields are in opposite directions it's like having 2 north poles facing each other.
@@PhysicsNinja Awesome. Thanks for response. I got it. Had to re-watch video a couple of times but I understand how to solve for the direction of induced current now. Ok, hopefully last question: to apply that to reality, are we saying the actual flow of electrons will actually be in the opposite direction of the blue arrow I-induced you labeled? If you would be so kind to possibly converse more offline? Please contact me: ryanmarshall13@outlook.com Thanks in advance.
@@ryanmarshall4741 if north pole of magnet is moved towards the coil then according to lenzes law the direction of induced current will be anticlockwise and if south pole is moved towards coil the direction of induced current will be clockwise .Am I right?? Now u tell me that if north pole of magnet is moved away and then south pole is moved away from coil respectively so, what will be induced current direction??
Isn't induced field supposed to be opposite when the distance between the magnet and coils get far from each other since the flux is increasing? This seems like opposite from what I have learned.
Hello, I'm stuck with using my right hand because from what I got the force and magnetic field lines are parallel, and I'm sure I'm doing something wrong
It would make it a lot lot simpler if you labeled the ends of the inductor N and S for each case but this was still really good.. Keeping the magnetic flux constant via generating a matching opposing magnetic field is interesting (I guess this would be obeying Newton's third law of motion - I just looked this up)
This does not make sense to me. Here in Norway the thumb is the force which is okay. But how are you able to find the current's direction without knowing the force. Don't you need to know two of the 3 vectors in the hand rule?
I don't think so.. as far as I know, left hand rule is to find the force direction and right hand rule for current direction. So we'd still use right hand rule, but idk I'm not sure of this hehe

this is from 6 years ago but is still views this concept from a much more understandable perspective. literally perfect. thanks so much
spent like 3 hours trying to understand lenz law, and your video just explained it in 11 minutes
Thank you!
Super helpful!! Nothing has helped me understand Lenz's Law until now, thank you so much
You got this Mila!
BEST explanation of right-hand rule. I think you just saved me from my test!
You cleared up my questions on induced current more than what my physics teacher accomplished in two weeks. Thanks so much, this was a lifesaver!
Was Trying to understand Lenz Law for my exam, could not find anything helpful. But at the exam day, found this video. ThankYou so much!!!

Tq sir very helpful... From india🇮🇳🇮🇳
THANK YOU THIS IS WHAT MY PHYSICS TEACHER COULDNT CONVEY TO ME
Just wondering what does it mean by B is the field lines crossing initially
Thank you so much! This video really cleared everything up for me. My teacher taught it a bit differently but I’m sticking to your method👍.
Sir please use the mic the sound will be better 😊 because explanation is crystal clear
😂❤😂❤ I understood lenz's law after was confused for many times
Great explanation!!
Jesus christ this is amazing.
thank you so much for the video better than any lecturer in my school really saved my ass before alevels
Thanks physics ninja!!

If we move the magnet towards the coil in such a way that the north pole of the magnet faces the coil, the coil will oppose its motion and will generate the north pole. It will repel magnet. Then the magnet will move away. Then coil will oppose that too. So the magnet will move towards the coil and so on.
We gave an initial push and the magnet started moving on its own. If magnet does so it will become self sustaining and will oppose the law of conservation of energy.
So will the magnet do this or not and why?
Please answer. My knowledge is not able to answer it.
I love your lectures by the way. 🥰🥰🥰
Thanx sir it helps me a lot ,to clear my concept
Glad i was able to help you. Dr. E.
very very very good conceptual information! Saving me on building my own tesla coil!!!
Amazing...I understood the concept really well..
Thanks physics ninja❤️❤️❤️❤️
Very clear explanation.Tq 🙏
Why does the galvanometer deflect to the right when pushing the north pole inside, since positive potential is on the left so it seems logical to me that it would point to the left?
Btw. Great video.
the right hand rule doesnt make sense
could you help ??
My question is how do you know which way the current is going around the coil in the first place? is it arbitrary?
In the first place there's no current going through the coil.
@@lukakusekovic9185 The current is induced in the coil due to change of magnetic flux by the movement of bar magnet
Thank you. Explained very well
Does anything change if the magnet comes from the other side?
Fully cleared my concept... ☺😊
The video was great and it was incredibly helpful, thank you so much!
One question sir , how did you determine the direction of field B ?
This is the basic problem he just discussed without applying the rules except saying in words written in books.
thank you! this is really helpful!
Thank you, I finally get it.
6 years old video but im still here, made me understand immediately, thank you🤍
Hi, I have a question. if the switch JUST got turned off on the solenoid, what would magnetic field on the solenoid be? it is going to be reduced, but still in the same direction I guess? (not looking at the inducing B yet. just the orignal B).
What would happen if the magnet was perpendicular to the axis of the coil and was moving from point A to point B of the side of the coil?
There’s two different directions of current for the same direction of magnetic fields when using right hand rule, I don’t get it?
The direction of the field is not important. It's the direction of the change of the magnetic field that is important.
Very clear and well explained, thank you.
YOU BLOODY LEGEND!!
Is the magnetic field within the coil uniform?
Doesn’t need to be, but it makes calculations a hell of a lot easier.
Thank you! ❤❤
Hi, I just want to know what will be the positive terminal of the coil??
The N side or S side??, When The North Pole is coming towards the coil
how did you know to draw I going downward in the first example?
Hmmm I’m not sure I understand your question. For the coil I just picked one direction to wrap the wire around in a coil. It’s completely arbitrary.
Thank you. Very helpful video.
Why are the magnetic lines coming OUT OF N and going into S? Also, what I want to know is if you had a nail running through the coil and you applied a current to that coil, can you figure out which direction the nail would go?

Are lenz's and faraday's laws the same?
What if the magnet was to the left of the solenoid? Would we use left hand rule?
I don't think so.. as far as I know, left hand rule is to find the force direction and right hand rule for current direction. So we'd still use right hand rule, but idk I'm not sure of this hehe
